Artificial Waters. 313 



Artificial sea water, Aqua marina arte facta. Water 5 

 gall, muriate of soda 5x, muriate of magnesia 3x, muriate of lime 

 3ij, sulphate of soda and sulphate of magnesia of each 3VJ ; dis- 

 solve ; dose 5iv, or as a bath. 



Water impregnated with fixed air, Carhonic acid. Aqua 

 acidulata cum acido carhonico, Acidum carhonicum. Put marble 

 in coarse grains into a bottle wetted beforehand, and add by 

 degrees a sufficient quantity of muriatic acid, at 10 deg. Baume, 

 to dissolve the marble ; pass the gas by means of elbowpipes 

 through two or three bottles, the first having only a small quantity 

 of water to absorb any muriatic acid that may come over, the 

 others containing between them about a gallon of water for each 

 half ounce of marble employed : an agreeable summer drink. 

 The muriatic acid in the residuum may be obtained for future 

 use, by adding oil of vitriol as long as any sediment falls. 



Single soda water. Aqua acidi carhonici. Impregnate 

 water by means of an apparatus made for the purpose, and which 

 will allow considerable pressure to be applied, with five or ten 

 times its bulk of carbonic acid gas (each ounce of marble yields 

 nearly two gall, of the gas), and transfer the impregnated water 

 into half-pint bottles, to be well corked and wired. The gas 

 escapes as soon as the bottle is opened, and gives the water an 

 agreeable piquancy. 



Carbonated lime water, Aqua calcaria acidula. Lime 

 water 1 pint, distilled water 2 pints; pass carbonic acid gas through 

 it, until the water, which at first is rendered cloudy, becomes 

 transparent again. Used in calculous complaints. 



Artificial Spa water, Aqua carhonatis aciduli sodoi mixta. 

 Water 5 gall. carl)onate of lime 3ij, carbonate of magnesia jj, 

 subcarlx)nate of s<xla 5vj, muriate of soda Sjss; dissolve, and pass 

 through it the carbonic acid from marble 3ij. 



Artificial chalybeate water. Aqua carhonatis aciduli Jerri. 

 Water impregnated with fixed air 1 pint, iron filings 5J ; keep in 

 a cool place for 24 hours : pour off the clear. 



Aqua supercarbonatis potass.c. Oil of vitriol 5ii), water 



jh. iij ; mix, and add gradually marble powder oiij ; pass the gas 



tliat is discharged through water 1 gall, with subcarb. of potash 



j dissolved in it, in a proper apparatus, to secure consiaerable 



icssure, and enable the l)ottles containing it to be corked with- 



iit letting the gas escape till drank. 



Double soda water, Aqim suhcarhonatis soda:. Prepared 

 by putting 1 gall, water and subcarb. of soda 5ij in bottles, and 

 passing carlxmic acid gas through it. Used largely as a cooling 

 beverage in summer : beneficial in calculous complaints.
